RESUMEN

This case report describes a 40-year-old male patient with severe cardiac failure due to eosinophilic granulomatosis with polyangiitis (EGPA) and myocarditis. The fast diagnostic approach with cardiac MRI (CMR) and immunosuppressive treatment with glucocorticoid and cyclophosphamide near-normalized the patient's cardiac function. Myocarditis due to EGPA is rare, however life-threatening, so a systematic approach and early CMR should be considered in patients with known asthma presenting with eosinophilia and cardiac involvement.

RESUMEN

Two cases of neonatal splenic hemorrhage with acute cardiorespiratory failure are described in this report. The first case involves a full-term neonate who was found unresponsive without any witnesses and could not be successfully resuscitated. A postmortem diagnosis revealed a splenic hemorrhage. Second case is an extremely premature neonate who experienced a witnessed cardiovascular collapse on the 14th day of life. Rapid cardiovascular support was administered, resulting in a positive outcome. While splenic hemorrhage is commonly associated with traumatic events, these cases highlight the need of considering spontaneous splenic hemorrhages as a potential cause of acute neonatal compromise, even in the absence of birth-related trauma (e.g., asphyxia, prolonged labor, clavicle fractures, brachial plexus injuries). This report emphasizes the importance of including splenic hemorrhage timely in the differential diagnosis of neonatal cardiorespiratory instability, especially in the absence of more common diagnoses, and discusses the challenges associated with its recognition and treatment.

RESUMEN

BACKGROUND: In acute heart failure (HF), reduced cardiac output, vasoconstriction and congestion may damage the intestinal mucosa and disrupt its barrier function. This could facilitate the leakage of bacterial products into circulation and contribute to inflammation and adverse cardiac remodelling. We aimed to investigate gut leakage markers and their associations with inflammation, infarct size and cardiac function. METHODS: We examined 61 ST-elevation myocardial infarction (STEMI) patients who developed acute HF within 48 hours of successful percutaneous coronary intervention (PCI). Serial blood samples were taken to measure lipopolysaccharide (LPS), LPS-binding protein (LBP), soluble cluster of differentiation 14 (sCD14) and intestinal fatty acid binding protein (I-FABP). Cumulative areas under the curve (AUCs) from baseline to day 5 were calculated. Serial echocardiography was performed to assess left ventricular ejection fraction (LVEF), global longitudinal strain (GLS) and wall motion score index (WMSI). Single-photon emission CT (SPECT) was performed at 6 weeks to determine infarct size and LVEF. RESULTS: I-FABPAUC correlated positively with infarct size (rs=0.45, p=0.002), GLS (rs=0.32, p=0.035) and WMSI (rs=0.45, p=0.002) and negatively with LVEF measured by SPECT (rs=-0.40, p=0.007) and echocardiography (rs=-0.33, p=0.021) at 6 weeks. LPSAUC, LBPAUC and sCD14AUC did not correlate to any cardiac function marker or infarct size. Patients, who at 6 weeks had above median GLS and WMSI, and below-median LVEF measured by SPECT, were more likely to have above median I-FABPAUC during admission (adjusted OR (aOR) 5.22, 95% CI 1.21 to 22.44; aOR 5.05, 95% CI 1.25 to 20.43; aOR 5.67, 95% CI 1.42 to 22.59, respectively). The same was observed for patients in the lowest quartile of LVEF measured by echocardiography (aOR 9.99, 95% CI 1.79 to 55.83) and three upper quartiles of infarct size (aOR 20.34, 95% CI 1.56 to 264.65). CONCLUSIONS: In primary PCI-treated STEMI patients with acute HF, I-FABP, a marker of intestinal epithelial damage, was associated with larger infarct size and worse cardiac function after 6 weeks.

RESUMEN

BACKGROUND: Hip fractures in the elderly are a common traumatic injury. Due to factors such as age and underlying diseases, these patients exhibit a high incidence of acute heart failure prior to surgery, severely impacting surgical outcomes and prognosis. OBJECTIVE: This study aims to explore the potential risk factors for acute heart failure before surgery in elderly patients with hip fractures and to establish an effective clinical prediction model. METHODS: This study employed a retrospective cohort study design and collected baseline and preoperative variables of elderly patients with hip fractures. Strict inclusion and exclusion criteria were adopted to ensure sample consistency. Statistical analyses were carried out using SPSS 24.0 and R software. A prediction model was developed using least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression. The accuracy of the model was evaluated by analyzing the area under the receiver operating characteristic (ROC) curve (AUC) and a calibration curve was plotted to assess the model's calibration. RESULTS: Between 2018 and 2019, 1962 elderly fracture patients were included in the study. After filtering, 1273 were analyzed. Approximately 25.7% of the patients experienced acute heart failure preoperatively. Through LASSO and logistic regression analyses, predictors for preoperative acute heart failure in elderly patients with hip fractures were identified as Gender was male (OR = 0.529, 95% CI: 0.381-0.734, P < 0.001), Age (OR = 1.760, 95% CI: 1.251-2.479, P = 0.001), Coronary Heart Disease (OR = 1.977, 95% CI: 1.454-2.687, P < 0.001), Chronic Obstructive Pulmonary Disease (COPD) (OR = 2.484, 95% CI: 1.154-5.346, P = 0.020), Complications (OR = 1.516, 95% CI: 1.033-2.226, P = 0.033), Anemia (OR = 2.668, 95% CI: 1.850-3.847, P < 0.001), and Hypoalbuminemia (OR 2.442, 95% CI: 1.682-3.544, P < 0.001). The linear prediction model of acute heart failure was Logit(P) = -2.167-0.637×partial regression coefficient for Gender was male + 0.566×partial regression coefficient for Age + 0.682×partial regression coefficient for Coronary heart disease + 0.910×partial regression coefficient for COPD + 0.416×partial regression coefficient for Complications + 0.981×partial regression coefficient for Anemia + 0.893×partial regression coefficient for Hypoalbuminemia, and the nomogram prediction model was established. The AUC of the predictive model was 0.763, indicating good predictive performance. Decision curve analysis revealed that the prediction model offers the greatest net benefit when the threshold probability ranges from 4 to 62%. CONCLUSION: The prediction model we developed exhibits excellent accuracy in predicting the onset of acute heart failure preoperatively in elderly patients with hip fractures. It could potentially serve as an effective and useful clinical tool for physicians in conducting clinical assessments and individualized treatments.

RESUMEN

AIM: Increased diagnostic awareness and specific disease treatments have changed the landscape of transthyretin cardiac amyloidosis (ATTR). Patients with wild-type ATTR (ATTRwt) are increasingly being diagnosed, potentially changing the clinical profile and prognosis compared with existing retrospective data. We aimed to study the clinical characteristics, distribution of red flags and prognosis of contemporary ATTRwt patients. METHODS: From January 1st 2017, to December 31st 2022, 213 consecutive patients were diagnosed with ATTRwt and prospectively followed up. Data on clinical characteristics, biomarkers, echocardiography findings, hospitalization due to worsening heart failure (WHF) and all-cause mortality were collected. RESULTS: A 37% increase in newly diagnosed patients from 2017-2019 (n = 90) vs. 2020-2022 (n = 123) was observed. The majority of patients presented with NAC disease stage I in the latter period (49% in 2017-2019 vs. 58% in 2020-2022, p = .16). Red flags were primarily cardiac-related, including elevated NT-proBNP, impaired left ventricular longitudinal systolic strain with an apical sparing pattern, heart failure with increased left ventricular wall thickness and elevated troponins. NAC disease stage I as well as low NT-proBNP levels (<1000 ng/L) were significantly associated with better survival (both p < .001). When compared with NAC disease stage II + III combined, patients with NAC disease stage I had a significantly lower risk of WHF hospitalization or death (log rank test: p = .0001). Independent predictors of the combined endpoint WHF hospitalization or death were NT-proBNP (HR 1.03 [95% CI 1.00-1.07], p < .049) and prior implantation of permanent pacemaker (HR 2.01 [1.30-3.11], p = .002). CONCLUSION: Increased diagnostic awareness resulted in a 37% increase in newly diagnosed patients in 2020-2022 vs. 2017-2019. As expected all-cause mortality but also the morbidity in terms of risk of hospitalization with WHF were significantly lower in patients with NAC disease stage I, as well as in those with low NT-proBNP levels <1000 ng/L. These findings underline the importance of continuous attention to diagnostic awareness, as early diagnosis is critical for initiating both general and specific ATTR treatment, thus improving prognosis.

RESUMEN

BACKGROUND: Despite the high burden of diabetes and cardiovascular risk factors in American Indian communities in the United States, prospective studies of heart failure (HF) in this population group are scarce, and the generalizability of previous HF risk scales may be limited. We developed a parsimonious HF risk prediction equation that accounts for relevant risk factors affecting American Indian communities, focusing on diabetes and kidney damage. METHODS AND RESULTS: A total of 3059 participants from the SHS (Strong Heart Study) (56±8 years of age, 58% women) were included. Five hundred seven developed HF. Progressively adjusted Cox proportional hazards models were used to identify risk factors for HF and HF subtypes. Predictors of risk at 5 and 10 years included older age (hazard ratio [HR], 1.79 [95% CI, 1.43-2.25]; HR, 1.68 [95% CI, 1.44-1.95]), smoking (HR, 2.26 [95% CI, 1.23-4.13]; HR, 2.08 [95% CI, 1.41-3.06]), macroalbuminuria (HR, 8.38 [95% CI, 4.44-15.83]; HR, 5.20 [95% CI, 3.42-7.9]), microalbuminuria (HR, 2.72 [95% CI, 1.51-4.90]; HR, 1.92 [95% CI, 1.33, 2.78]), and previous myocardial infarction (HR, 6.58 [95% CI, 2.54-17.03]; HR, 3.87 [95% CI, 2.29-6.54]), respectively. These predictors, together with diabetes diagnosis and glycated hemoglobin were significant at 10 and 28 years. High discrimination performance was achieved (C index, 0.81 [95% CI, 0.76-0.84]; C index, 0.78 [95% CI, 0.75-0.81]; and C index, 0.77 [95% CI, 0.74-0.78] at 5, 10, and up to 28 years of follow up, respectively). Some associations varied across HF subtypes, although diabetes, albuminuria, and previous myocardial infarction were associated with all subtypes. CONCLUSIONS: This prospective study of HF risk factors in American Indian communities identifies that smoking, body mass index, and indicators of diabetes control and kidney damage (glycated hemoglobin and albuminuria) are major determinants of HF. Our findings can improve HF risk assessment in populations with a high burden of diabetes.

RESUMEN

BACKGROUND Lyme carditis typically presents with atrio-ventricular block; however, other cardiac manifestations, including varying EKG changes, myopericarditis and new-onset heart failure, can occur. CASE REPORT We report a case of a 52-year-old woman with past medical history significant for hypertension, chronic obstructive pulmonary disease, and chronic back pain who presented with new-onset heart failure in the setting of Lyme carditis. She presented with exertional dyspnea requiring supplemental oxygen, subjective fever, chills, fatigue, and arthralgia of 2-week duration. Her vital signs were consistent with hypotension and persistent bradycardia. An EKG displayed T-wave flattening in the anterior pre-cordial leads. Further work-up was suggestive of bilateral pulmonary edema and interstitial infiltrates, which required antibiotics and diuretics. Echocardiography demonstrated new-onset mildly depressed LV systolic dysfunction. Interestingly, coronary CTA revealed coronary arteries with no evidence of stenosis or plaque. She was found to have positive Lyme IgM and lgG antibodies. A diagnosis of Lyme myocarditis was considered and her antibiotic course was extended following multidisciplinary consensus. CONCLUSIONS This case report seeks to create awareness of the varying and atypical presentations of Lyme carditis, including new-onset heart failure in a patient without prior history of ischemic heart disease and uncommon EKG changes.

RESUMEN

Myocarditis (MC) is defined as an immunological inflammatory reaction with various etiologies, clinical presentations and prognoses within the myocardium. Currently, parvovirus B19 (PVB19) has become the main factor leading to this disease, replacing the previously dominant viruses A and B. In the case of chronic heart failure with subsequent dilated cardiomyopathy, approximately 67% have a viral etiology, and most of them are the result of PVB19 infection. However, the analysis showed a correlation between PVB19 infection and the risk of developing inflammatory dilated cardiomyopathy (DCMi). PVB19 is detected in 23% of patients with DCMi. Chronic infection may also contribute to progressive left ventricular failure in patients with a history of MC. The above effect suggests the active replication of PVB19 only in heart biopsies with inflammation due to MC or DCMi. Moreover, the supply of IFN-ß to suppress the active transcription of PVB19 accompanied by DCMi over a period of 6 months results in the normalization of NT-proBNP and an improvement in LVEF along with NYHA performance. The small number of reports on this topic and inaccuracies resulting from constantly conducted research and ongoing changes make it impossible to clearly answer the question of whether PVB19 is a factor inducing de novo MC and DCM or only accompanies the above conditions. However, large clinical cohort studies lead to the perception of PVB19 as a viral etiological agent capable of causing de novo MC together with DCMi.

RESUMEN

BACKGROUND: Patients with diabetes have an increased risk of developing heart failure with preserved ejection fraction (HFpEF). This study aimed to compare indices of myocardial deformation and perfusion between patients with type 2 diabetes mellitus (T2DM) with and without HFpEF and to investigate the relationship between myocardial strain and perfusion reserve. METHODS: This study included 156 patients with T2DM without obstructive coronary artery disease (CAD) and 50 healthy volunteers who underwent cardiac magnetic resonance (CMR) examination at our center. Patients with T2DM were subdivided into the T2DM-HFpEF (n = 74) and the T2DM-non-HFpEF (n = 82) groups. The parameters of left ventricular (LV) and left atrial (LA) strain as well as stress myocardial perfusion were compared. The correlation between myocardial deformation and perfusion parameters was also assessed. Mediation analyses were used to evaluate the direct and indirect effects of T2DM on LA strain. RESULTS: Patients with T2DM and HFpEF had reduced LV radial peak systolic strain rate (PSSR), LV circumferential peak diastolic strain rate (PDSR), LA reservoir strain, global myocardial perfusion reserve index (MPRI), and increased LA booster strain compared to patients with T2DM without HFpEF (all P < 0.05). Furthermore, LV longitudinal PSSR, LA reservoir, and LA conduit strain were notably impaired in patients with T2DM without HFpEF compared to controls (all P < 0.05), but LV torsion, LV radial PSSR, and LA booster strain compensated for these alterations (all P < 0.05). Multivariate linear regression analysis demonstrated that LA reservoir and LA booster strain were independently associated with global MPRI (ß = 0.259, P < 0.001; ß = - 0.326, P < 0.001, respectively). Further, the difference in LA reservoir and LA booster strain between patients with T2DM with and without HFpEF was totally mediated by global MPRI. Global stress PI, LA booster, global rest PI, and global MPRI showed high accuracy in diagnosing HFpEF among patients with T2DM (areas under the curve [AUC]: 0.803, 0.790, 0.740, 0.740, respectively). CONCLUSIONS: Patients with T2DM and HFpEF exhibited significant LV systolic and diastolic deformation, decreased LA reservoir strain, severe impairment of myocardial perfusion, and elevated LA booster strain that is a compensatory response in HFpEF. Global MPRI was identified as an independent influencing factor on LA reservoir and LA booster strain. The difference in LA reservoir and LA booster strain between patients with T2DM with and without HFpEF was totally mediated by global MPRI, suggesting a possible mechanistic link between microcirculation impairment and cardiac dysfunction in diabetes. Myocardial perfusion and LA strain may prove valuable for diagnosing and managing HFpEF in the future.

RESUMEN

Despite the presence of various signs of cardiac amyloidosis ("red flags"), the introduction into routine practice of new non-invasive diagnostic methods (Speckle Tracking technology using echocardiography, myocardial scintigraphy with technetium pyrophosphate, genetic testing, screening for free light chains of immunoglobulins to exclude AL-amyloidosis), which have high specificity and sensitivity, transthyretinic (ATTR) cardiomyopathy is still a difficult to diagnose disease, especially in the early stages when treatment is most effective. The article presents a clinical case of ATTR-amyloidosis with predominant heart damage, manifested by severe diastolic heart failure resistant to treatment. The timing, from the moment of the first episode of decompensation of heart failure to death, is 4 months, which confirms the rapid progression of severe biventricular dysfunction of the heart. Despite the presence of cardiac and extracardial "red flags" of ATTR-amyloidosis in the patient, the diagnosis was established at autopsy. The paper analyzes possible errors of early diagnosis at the outpatient and inpatient stages of patient management.

RESUMEN

Targeting cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) with specific antibody offers long-term benefits for cancer immunotherapy but can cause severe adverse effects in the heart. This study aimed to investigate the role of anti-CTLA-4 antibody in pressure overload-induced cardiac remodeling and dysfunction. Transverse aortic constriction (TAC) was used to induce cardiac hypertrophy and heart failure in mice. Two weeks after the TAC treatment, mice received anti-CTLA-4 antibody injection twice a week at a dose of 10 mg/kg body weight. The administration of anti-CTLA-4 antibody exacerbated TAC-induced decline in cardiac function, intensifying myocardial hypertrophy and fibrosis. Further investigation revealed that anti-CTLA-4 antibody significantly elevated systemic inflammatory factors levels and facilitated the differentiation of T helper 17 (Th17) cells in the peripheral blood of TAC-treated mice. Importantly, anti-CTLA-4 mediated differentiation of Th17 cells and hypertrophic phenotype in TAC mice were dramatically alleviated by the inhibition of interleukin-17A (IL-17A) by an anti-IL-17A antibody. Furthermore, the C-X-C motif chemokine receptor 4 (CXCR4) antagonist AMD3100, also reversed anti-CTLA-4-mediated cardiotoxicity in TAC mice. Overall, these results suggest that the administration of anti-CTLA-4 antibody exacerbates pressure overload-induced heart failure by activating and promoting the differentiation of Th17 cells. Targeting the CXCR4/Th17/IL-17A axis could be a potential therapeutic strategy for mitigating immune checkpoint inhibitors-induced cardiotoxicity.

RESUMEN

Severe systemic right ventricular failure with tricuspid regurgitation is associated with poor prognosis. Here, we report a case of 49-year-old patient who experienced severe systemic right ventricular failure following atrial switch. We chose the surgical strategy for this challenging case using comprehensive four-dimensional imaging. The patient underwent tricuspid valve repair and cardiac resynchronization therapy and recovered with improved cardiac function and regulated tricuspid valve regurgitation.

RESUMEN

Objective: To analysis the risk factors for major adverse cardiovascular event (MACE) in pregnant women with valvular heart disease (VHD) and to construct a risk prediction model. Methods: The clinical data of 245 pregnant women with VHD who were hospitalized in Beijing Anzhen Hospital from January 1, 2012, to June 1, 2023 were retrospectively analyzed, including general information, pre-pregnancy and pregnancy-associated cardiac conditions, and MACE. Univariate analysis and logistic regression models were employed to identify risk factors for MACE during pregnancy among pregnant women with VHD. Furthermore, a predictive model was constructed and internal validation was conducted using bootstrap techniques. Results: (1) Among 245 pregnant women with VHD, the incidence of MACE was 18.0% (44/245), and the most common MACE was heart failure (61.4%, 27/44). The mitral valve was the most frequently affected valve (64.9%, 159/245). Prior to pregnancy, the most common type of valve surgery undertaken was mechanical valve replacement, representing 31.4% (77/245) of surgeries. In contrast, among those pregnant women who did not undergo valve surgery before pregnancy, the most common lesion type was mitral regurgitation (17.6%, 43/245). (2) Comparing the maternal and infant outcomes of warfarin, low molecular weight heparin (LMWH) and LMWH sequential with warfarin, the fetal loss rate (36%, 15/42) and malformation rate (7%, 3/42) were the highest, but the MACE rate (12%, 5/42) was the lowest in warfarin group. The fetal loss rate (1/19), malformation rate (1/19) and artificial valve thrombosis rate (0) of LMWH sequential with warfarin were the lowest, and the fetal loss rate and artificial valve thrombosis rate of the three anticoagulation methods were statistically significant (all P<0.05). (3) There were no significant differences in gestational age, age of diagnosis of heart disease, weight at delivery, pre-pregnancy body mass index, proportion of multiparous women and chronic medical history between women with MACE and those without MACE (all P>0.05). (4) Binary logistic regression analysis identified the following as risk factors for MACE during the second trimester of pregnancy among pregnant women with VHD: pre-pregnancy cardiac symptoms, history of corrective surgery for congenital heart disease, pregnancy risk grade Ⅴ, anticoagulation with LMWH during pregnancy, and arrhythmia (all P<0.05). Based on the results of multivariate analysis, a receiver operating characteristic curve was constructed, with an area under the curve of 0.837, indicating good discriminative ability. The calibration plot demonstrated a close alignment between the standard curve and the calibration prediction curve, suggesting excellent calibration of the model. Conclusions: Pregnant women with VHD are at a high risk of experiencing MACE during gestation. Five risk factors, including pre-pregnancy cardiac symptoms, history of corrective surgery for congenital heart disease, pregnancy risk grade Ⅴ, anticoagulation with LMWH, and arrhythmia, could aid in identifying high-risk pregnant women.

RESUMEN

BACKGROUND: Recent studies show Silent Myocardial Infarction (SMI) as a quite frequent event. However, regarding severe tertiary care patients that frequently present consequences of Coronary Artery Disease (CAD) and Left Ventricular Dysfunction (LVD), the occurrence of this manifestation is unexpected and its associated factors aren't clear in the literature. AIM: To compare clinical, laboratorial, ventricular and angiographic factors between silent and classical presentation of MI in patients with CAD and LVD. METHODS: Patients with multivessel CAD with over 70 % obstructive lesions and LVD with EF less than 35 % were evaluated for MASS VI trial and later included in the present study. The ventricular function and coronary assessment were measured by echocardiography and SYNTAX score, respectively. The population was stratified in a SMI group and Clinically Manifested Myocardial Infarction (CMMI) group based on MI presentation for a comparison of medical parameters. RESULTS: From 132 patients, 47 (35.6 %) were classified as SMI and 85 (64.4 %) as CMMI. No differences were observed between groups regarding age, sex, diabetes mellitus, SYNTAX score, or collateral circulation. Higher proportion of NYHA II classification, inferior wall MI and lower creatinine clearance were found in SMI group. After multivariate analysis, peripheral diabetic neuropathy (OR = 4.6 [1.1‒12.7] p = 0.032) and inferior wall MI (OR = 4.1 [1.5‒11.4] p = 0.007) were significantly associated with SMI. CONCLUSION: Peripheral diabetic neuropathy and inferior wall MI were associated with SMI presentation. Overall, associated factors tend to be similar comparing SMI and CMMI, but in the specific population of diabetic patients with chronic neuropathy a special care should be taken.

RESUMEN

BACKGROUND: There are diverse indications for heart transplantation (HTx), often categorized into ischemic (ICM) and nonischemic (NICM) cardiomyopathy. Although there is extensive research comparing the outcomes for these disease processes following certain therapeutic interventions, there are limited data on how recipient etiology impacts post-HTx survival. Our investigation seeks to identify this relationship. METHODS: We conducted a retrospective analysis using adult HTx patients from the United Network for Organ Sharing database between 2000 and 2021. Patients with a combined heart-lung transplant or previous HTx were excluded. ICM included coronary artery disease (CAD) and ischemic dilated cardiomyopathy. NICM included nonischemic dilated (NIDCM), hypertrophic (HCM), and restrictive (RCM) cardiomyopathy. Overall survival was analyzed using Kaplan-Meier curves, log-rank tests, and multivariable Cox regression models. RESULTS: A total of 42 268 patients were included in our study. Recipients with ICM were older and more likely to be males, obese, diabetics, and smokers. We found that patients with ICM had an increased incidence of transplant CAD (OR = 1.23, p < 0.001) and risk of mortality (hazard ratio [HR] = 1.22, p < 0.001) compared to NICM. When NICM was expanded, RCM had a similar hazard risk compared to ICM (HR = 1.03, p = 0.650), whereas both NIDCM (HR = 0.81, p < 0.001) and HCM (HR = 0.70, p < 0.001) had improved survival. CONCLUSION: Our study provides evidence to suggest that ICM has decreased survival when compared to NICM. When NICM was expanded, RCM was found to have an increased mortality risk similar to ICM, whereas NIDCM and HCM both had superior outcomes. The clinical implication of this investigation will allow clinicians to better understand the prognosis of certain patient groups.

RESUMEN

BACKGROUND: Currently, the treatment outcomes for complex congenital arteriovenous malformations (AVMs) remain unsatisfactory. This article reports on the utilization of an abdominal aortic stent graft, in conjunction with embolization techniques, for managing acute heart failure triggered by complex congenital arteriovenous malformations in the lower limb. CASE PRESENTATION: We present a case involving a patient with congenital AVMs in the lower limb, who had suffered from prolonged swelling in the left lower limb and recently developed symptoms of heart failure. At the age of 67, the patient was definitively diagnosed with a complex congenital AVMs in the lower limb. This article delves into the practical experiences and limitations encountered in employing an abdominal aortic stent graft, coupled with embolization, to address acute heart failure caused by complex congenital AVMs in the lower limb. CONCLUSIONS: Our article presents the initial report on the challenges and limitations encountered in treating acute heart failure triggered by complex congenital AVMs in the lower limb, utilizing a combination of abdominal aortic stent graft placement and embolization techniques.

RESUMEN

Pulmonary hypertension includes a diverse set of conditions defined by a mean pulmonary artery pressure greater than 20 mm Hg found during right heart catheterization that can lead to right-sided heart failure and death if untreated. The most common cause of pulmonary hypertension is left-sided heart failure, followed by chronic obstructive lung disease. Pulmonary hypertension presents as unexplained dyspnea on exertion and possible findings of right-sided heart failure. The diagnosis is commonly delayed because the symptoms are often attributed to underlying heart or lung disease. Echocardiography is the initial study of choice, and findings can suggest a low, intermediate, or high risk of pulmonary hypertension. Right heart catheterization is the standard of care for diagnosing and classifying pulmonary hypertension, and the results may inform treatment. Patients with pulmonary hypertension should be referred to a center specializing in treatment. Patients with pulmonary hypertension have a high risk of perioperative complications, and detailed specialty preoperative evaluation is recommended. Physicians should counsel patients of childbearing age with pulmonary hypertension to prevent pregnancy to avoid worsening the severity of pulmonary hypertension and fetal loss. Pulmonary hypertension is severe, chronic, progressive, and challenging to treat; therefore, family physicians should update the patient's immunization status, screen for and address mental health conditions, and discuss goals of care and advance directives with patients.

RESUMEN

Whipple disease is a rare systemic illness associated with weight loss, diarrhea, and arthralgia. Asymptomatic carriage is common, but the disease can be complicated by cardiac involvement and may result in culture-negative endocarditis. Cardiac manifestations of the disease can lead to death. This report presents the case of a 66-year-old man with Whipple disease and biventricular heart failure with cardiogenic shock. Medical therapy followed by successful replacement of the aortic and mitral valves resulted in substantial improvement.

RESUMEN

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has gained traction as a bridge to heart transplantation (HT) but remains associated with increased waitlist mortality. This study explores whether this risk is modified by underlying heart failure (HF) etiology. METHODS: Using the Organ Procurement and Transplantation Network registry, we conducted a retrospective review of first-time adult HT candidates from 2018 through 2022. Patients were categorized as "ECMO", if ECMO was utilized during the waitlisting period, or "No ECMO" otherwise. Patients were then stratified according to the following HF etiology: ischemic cardiomyopathy (CMP), dilated nonischemic CMP, restrictive CMP, hypertrophic CMP, and congenital heart disease (CHD). After baseline comparisons, waitlist mortality was characterized for ECMO and HF etiology using the Fine-Gray regression. RESULTS: A total of 16 143 patients were identified of whom 7.0% (n = 1063) were bridged with ECMO. Compared to No ECMO patients, ECMO patients had shorter waitlist durations (46.3 vs. 185.0 days, p < 0.01) and were more likely to undergo transplantation (75.3% vs. 70.3%, p < 0.01). Outcomes analysis revealed that ECMO was associated with increased mortality risk (subdistribution hazard ratio [SHR]: 3.42, p < 0.01), a risk that persisted in all subgroups and was notably high in CHD (SHR: 4.83, p < 0.01) and hypertrophic CMP (SHR: 9.78, p < 0.01). HF etiology comparison within ECMO patients revealed increased mortality risk with CHD (SHR: 3.22, p < 0.01). Within No ECMO patients, hypertrophic CMP patients had lower mortality risk (SHR: 0.64, p = 0.03). CONCLUSIONS: The increased waitlist mortality risk with ECMO persisted after stratification by HF etiology. These findings can help decision-making surrounding candidacy for cannulation and prognostic evaluation.
